Answers

Answer 1

The number of the outcomes at two of the coins will turn up as head is 11

What is a combination?

In mathematics, a combination or combinations are all the possible groupings that can be made of a given number of elements, without repeating them and regardless of the order in which they are found.

To solve this problem the formula and the combination procedure we must use is:

C(n/r) = n! / [(n-r)! *r!]

Where:

C(n/r) = combinationn = total number of objectsr = number of selected objects! = factorial of the number

Information about the problem:

Number of outcomes in which 0 coins turns heads = 4C0Number of outcomes in which 1 coins turns heads = 4C1Number of outcomes in which 2 coins turns heads = 4C2Total number of outcomes = 4C0 + 4C1 + 4C2

Applying the combination formula we have:

C(n/r) = n! / [(n-r)! *r!]

C(4/2) = 4! / [(4-2)! *2!]

C(4/2) = 4! / [(2)! *2!]

C(4/2) = 4*3*2! / [(2)! *2!]

C(4/2) = 4*3/2!

C(4/2) = 6

C(4/1) = 4! / [(4-1)! *1!]

C(4/1) = 4! / [(3)! *1!]

C(4/1) = 4*3! / [(3)! *1!]

C(4/1) = 4 / [1!]

C(4/1) = 4

C(4/0) = 4! / [(4-0)! *0!]

C(4/0) = 4! / [(4)! * 0!]

C(4/0) = 1

Total number of outcomes = 4C0 + 4C1 + 4C2

Total number of outcomes = 1 + 4 + 6

Total number of outcomes = 11

what is the area under the normal distribution that is between the mean and one standard deviation away from the mean?

Answers

About 68% of the area is covered by one standard deviation above and below the mean, therefore one standard deviation above the mean corresponds to 34% of the area. Thus, we have 84% after adding the 50% below the mean and the 34% above the mean.

A normality assumption with a zero mean and a standard error of one is referred to as the typical normally distributed. The standard normal distribution is centered at zero, and the standard deviation indicates how much a specific measurement deviates from the mean.

Sixty-eight percent of the observations for the normal distribution are within one standard deviation of the mean, ninety-five percent are within two standard deviations of the mean, and ninety-nine percent are within three standard deviations of the mean.

According to the exterior angle theorem, the exterior angle that results from stretching a triangle's side is equal to the sum of the dimensions of the triangle's two opposed interior angles.

What is theorem of exterior angles?

According to the exterior angle theorem, the exterior angle that results from stretching a triangle side is equal to the sum of the dimensions of the triangle's two opposed interior angles. Three internal angles in a triangle or polygon always add up to 180 degrees. This theorem is applied to each of the outer angles, which total six.

Here,

Given :

With the help of the triangle's well-known features, we can validate the exterior angle theorem.

Think about an ABC.

The total of the three angles is 180 degrees (angle sum property of a triangle) ——- Equation 1: (A+B)/180 ——- Example 2 (rewriting equation 1)

e = 180 - c

——- Equivalent 3 (linear pair of angles)

Equation 3 may be solved for by substituting the value of c.

e = 180 - [180 - (a + b)]

e = 180 - 180 + (a + b)

e = a + b.

=> m∠A = m∠G

=> m∠DMG > m∠A

So , its proven that:

=> m∠DMG > m∠G

and

=> A-D-M

So,

AD = DM

=> AD <AM

When taking out a loan, the borrower must provide collateral such as a car or home to reduce the risk to the lender and increase the chances of the loan being approved. This includes rent, monthly bus pass, savings, student loan payment, and other expenses.

What do you mean by loan?

A loan is a type of debt that is typically provided by a financial institution such as a bank, credit union, or finance company. The purpose of a loan is to provide the borrower with a large sum of money that they may not have readily available, which they must then pay back over a set period of time with interest.

There are various types of loans, including personal loans, car loans, home loans, and student loans. Personal loans are unsecured loans that can be used for a variety of purposes, such as debt consolidation or home improvement. Car loans are used specifically to purchase a vehicle, while home loans are used to purchase a home. Student loans are designed to help pay for education expenses.

When taking out a loan, the borrower is typically required to provide some form of collateral, such as a car or a home, to secure the loan. This helps to reduce the risk to the lender and increases the chances of the loan being approved.

1. Rent: 30% of $3,850 = $1,155.

The monthly interest rate for the principal is 0.64%

How to determine the monthly rate?

Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods.

The formula for compound interest is

A = P(1 + r/n)^(nt)

where:

A = the future value of the investment/loan, including interest

P = the principal investment amount (the initial deposit or loan amount)

r = the annual interest rate (decimal form)

n = the number of times that interest is compounded per year

t = the number of years the money is invested or borrowed for

Since the annual interest rate (r) is 7.7%. The monthly interest rate can be calculated by dividing the annual interest rate by 12 (There are 12 months in a year).

Thus, monthly interest rate = 7.7 / 12 = 0.64%

geometry : find the value of x

Answers

Answer:

x = 7

Step-by-step explanation:

In a triangle(3 sides), the total number of degrees is 180 degrees.

In a quadrilateral(4 sides), the total number of degrees is 360 degrees.

^^ Now convert this into a formula

Let's say s = number of sides

d = total degrees

s:       d:

3 --> 180

4 --> 360

Hence, the relation between s and d is:

(s-2)*180

Let's test this relation:

3:

(3-2)*180 =  ==> plugin 3 for s in (s-2)*180

1*180 = 180 √

4:

(4-2)*180 =  ==> plugin 4 for s in (s-2)*180

2*180 = 360 √

Now apply this formula to an 8-sided figure:

s = 8

(s-2)*180 =

(8-2)*180 =   ==> plugin 8 for s in (s-2)*180

6*180 = 1080 total degrees in the 8-sided figure

Since all 8 sides in the 8-sided figure are equal, all 8 angles are equal as well.

Hence, the measure of each angle is:

1080 / 8 = 135 degrees

Hence:

16x + 23 = 135  ==> solve for x

16x = 112  ==> subtract 23 on both sides to isolate x

x = 7  ==> divide both sides by 16 to isolate x

A high school basketball coach wants to see whether there is a linear relationship between player height, x, and the number of points scored in a game by basketball players in the coach's state, y.

O It cannot be determined whether the linear relationship between player height and number of points scored for basketball players in the coach's state is positive or negative.
O We can be 95% confident that wind speed decreases, on average, between 1.20 knots and 1.42 knots for each millibar increase in minimum pressure.

Answers

The answer is C. There is a positive linear relationship between player height and number of points scored for basketball players in the coach's state.

A confidence interval is a range of values that is calculated from the data and is believed to contain the true population parameter with a certain level of confidence, in this case 96%. The slope of the regression line is the average change in y for a one unit change in x, which represents the direction and strength of the relationship between x and y.

The confidence interval for the slope is (−0.432,1.844), which does not include 0, which means that the slope is not equal to 0. If the slope were 0, there would be no relationship between player height and points scored. The fact that the confidence interval is positive means that the slope is positive, which indicates a positive linear relationship between player height and number of points scored.

find the volumes of the solids generated by revolving the regions about the given axes. If you think it would be better to use washers in any given instance, feel free to do so. The region bounded by y = 2x - x^2 and y = x about the line x=1

Answers

The volume of the solid generated by revolving the region bounded by y = 2x - x^2 and y = x about the line x=1 can be found using the method of cylindrical shells. The method involves slicing the solid into thin cylindrical shells, finding the volume of each shell, and then summing the volumes of all the shells to find the total volume of the solid.

We start by finding the equations for the two curves:

y = 2x - x^2,

y = x

We then find the points of intersection between the two curves:

2x - x^2 = x

x^2 - x - 2 = 0

x = 2 or x = -1

Since the solid is generated about the line x=1, we only consider the part of the region that lies to the right of x=1, which corresponds to x=2. The radius of each cylindrical shell is equal to the difference between the x-coordinate of the upper curve and x=1, which is 1. The height of each shell is equal to the difference between the y-coordinates of the two curves at x=2, which is (2x - x^2) - x = 2 - 4 = -2.

The volume of cylindrical shell is:

V = πr^2h

Plugging in the values:

V = π * (1^2) * (-2)

V = -2π

The total volume of the solid is the sum of the volumes of all the cylindrical shells, which is just -2π. The volume is negative because the height of each shell is negative, which indicates that the solid is being generated in the opposite direction.

One solution contains 2 parts salt to 8 parts water, and another contains 3 parts salt 5 parts water. How much of each should be mixed together in order to obtain 280 quarts of a solution that is 3 parts salt to 7 parts water? Please help very urgent!

Answers

In a case whereby one solution contains 2 parts salt to 8 parts water, and another contains 3 parts salt 5 parts water.  the number of each part that should be mixed together in order to obtain 280 quarts of a solution that is 3 parts salt to 7 parts water are: x = 160 quarts and 120 quarts  respectively.

How can the number of each part that should be mixed be calculated?

The concept that will be used here is simplification

The salt concentration  can be expressed by turning them to decimal form and these area;

Solution A: [2/(2 + 8)]

= [2/10]

= 0.20 salt

We can as well expresss the Solution B in term of fraction as:

: [3/(3 + 5) ]

= [3/8 ]

= 0.375 salt

We can as well express the Mixed Solution in term of fraction we can be done as

:[ s/(3 + 7)]

= 3/10

= 0.30 salt

The mixture is said to be 280 quarts, however in the case whereby  0.375 salt can found in the mixed solution that is denoted as " x" , we can know the  0.20 salt,  which can be expressed as [y = 280 – x]

Then we can compute the typical mixture equation as :

[0.375x + 0.20(280-x)]  = [0.30(280)]

If we simplify we have

[0.375x + 56 - 0.20x] = 84

It can be simplied further as

[0.375x - 0.20x + 56 – 56] = [84 – 56]

Then after the summation from the left sides we have

[0.375x - 0.20x] = 28

[0.175x ]= 28

Then, we can find the value of x as

x= 28/0.175

x = 160

Since the value of x is known we can find the value of Y as :

y = [280 – x]

y = [280 – 160]

Then the value of  y can be expressed as :

y = 120

The simple events in this ranking experiment are C-D-P, C-P-D, D-C-P, D-P-C, P-C-D, P-D-C where all of the simple events have the same probability, 1/6.

The simple events in this ranking experiment are the 6 possible ways the individual can order the three glasses of cola: C-D-P, C-P-D, D-C-P, D-P-C, P-C-D, P-D-C.

Since the individual's preferences are assumed to be random and the same cola has been put into all three glasses labeled C, D, and P, each of the 6 possible ways the individual can order the glasses (C-D-P, C-P-D, D-C-P, D-P-C, P-C-D, P-D-C) are equally likely.

This means that each of the 6 simple events has a probability of 1/6, or 0.1667. This is because if each ordering of the glasses is considered an outcome, there are 6 equally likely outcomes. The probability of any one of the outcomes is 1 divided by the total number of outcomes, or 1/6.

Cost of the item in both cases are (a) $21 (b) $21.6 and (c) Lower price of the item is when applied 20% discount first and then $3 off.

What is Percentage?

Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

Percentage is usually denoted by the symbol '%'.

(a) Original price of the item = $30

After 20% discount, price of the item = 30 - (30 × 20%)

                                                              = 30 - (30 × 0.2)

                                                              = $24

After $3 off, price of the item = $24 - $3 = $21

(b) Original price of the item = $30

After $3 off, price of the item = $30 - $3 = $27

After 20% discount, price of the item = 27 - (27 × 20%)

                                                             = $21.6

(c) The lower price is when applied 20% discount first and then $3 off.

The confidence interval is then (0.2155 - 0.0147) +/- (2 * 0.0347) = 0.201 +/- 0.0694, or (0.1316, 0.2694). This indicates that, on average, coached students gain 0.201 points more than uncoached students, with 99% confidence that the true difference lies between 0.1316 and 0.2694.

16^x + 3 = 4^ (x+1)

solve for x with steps please​

Answers

To solve for x in the equation 16^x + 3 = 4^ (x+1), follow these steps:

Isolate the x terms on one side of the equation by subtracting 3 from both sides:
16^x + 3 - 3 = 4^ (x+1) - 3
16^x = 4^ (x+1) - 3
Take the logarithm of both sides to get rid of the exponential functions:
log16 (16^x) = log16 (4^ (x+1) - 3)
x = log16 (4^ (x+1) - 3) / log16 (16)
Use the logarithmic identity logb (a^c) = c * logb (a) on the right side:
x = (x + 1) * log16 (4) / log16 (16)
Simplify the right side by using logarithmic identities:
x = (x + 1) * log16 (2^2) / log16 (2^4)
x = (x + 1) * 2 / 4
Solve for x by dividing both sides by x + 1 and multiplying by 4:
x * 4 / (x + 1) = 2
4x = 2x + 2
2x = 2
x = 1
Therefore, the solution for x is x = 1.

Find the volume of a right circular cone
that has a height of 19 ft and a base with a
diameter of 18.7 ft. Round your
answer to
the nearest tenth of a cubic foot.

Answers

Answer:

V = 31,667.8 cubic ft

Step-by-step explanation:

The volume of a right circular cone can be calculated using the formula:

V = (π * r^2 * h) / 3

Where r is the radius of the base and h is the height of the cone.

First, let's find the radius:

r = diameter / 2 = 18.7 ft / 2 = 9.35 ft

Now, we can plug in the values for r and h into the formula:

V = (π * 9.35^2 * 19) / 3 = (π * 87.5295 * 19) / 3 = (1670.20355 * 19) / 3 = 31,667.76 cubic ft

Rounding to the nearest tenth of a cubic foot, we get:

V = 31,667.8 cubic ft

1/3 r^2h
1/3 x 9.35^2 x 19
1/3 5218.27 ft (rounded to 2 d.p)
volume =1739.42 ft (rounded to 2 d.p)

the students in a first-grade class were all asked to time how long (in seconds) they could hold their breath. the results were tallied and are presented in the following histogram. how many of those students held their breath greater than 12.5 but less than 15.5 seconds?

Answers

Based on the histogram, 13 students held their breath for greater than 12.5 seconds but less than 15.5 seconds.

In a first-grade class, students measured how long they could hold their breath. The results were shown on a graph called a histogram. To see how many students held their breath between 12.5 and 15.5 seconds, we need to look at the bars on the graph between those times. The number of students is shown by the height of each bar.

We can see that there are 2 students who held their breath between 12.5 and 13.5 seconds. There are 5 students who held their breath between 13.5 and 14.5 seconds. And there are 6 students who held their breath between 14.5 and 15.5 seconds. To find out the total number of students, we add the heights of the bars together.

So:

2 + 5 + 6 = 13

Hence, there are 13 students who held their breath between 12.5 and 15.5 seconds.
